Patented Dec. 27, 1921.

Application filed September 18, 1919. Serial No. 324,580.

g all whomit may concern:

Be it known that I, MAX O'r'ro CLAUss, a citizen of Germany, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Skein-VVinding Mechanism, do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to an improved skein winding mechanism and has for its primary object to, provide a relatively simple mechanism for rapidly winding the yarn, cotton, silk or other thread into skeins inthe manner shown in my pending application for patent filed August 1st, 1919,

' Serial Number 314647.

Genericall considered, the present inven-- tion compre ends the provision of means for imparting to a flier arm or thread carrier a composite movement in two directions to thereby wind the thread in the desired manner around the spaced parts of a skein holder.

More specifically, the invention consists in the provision of a shaft mounted for axial and rocking or "rotary movement, the said shaft having a flier fixed to one of its ends to operate in conjunction with the skein holder of the form shown in my said application. For the operation of this shaft in a positive manner I provide a pair of cams and means operatively connected to the shaft and actuated by one of such cams for transmitting an axial movement to the shaft, and additional means also operatively connected to the shaft and actuated by the other cam for imparting a rocking or rotary movement to the shaft.

I further contemplate the provision of a skein winding mechanism as above characterized, the several .parts of which are ofsimple form, not liable to get out of order and which will operate in a highly efficient and reliable manner.

With the above and other objects in view, my invention resides. in an improved skein winding mechanism as above characterized and in the form, construction and relative arrangement of itsseveral parts as will be hereinafter more fully described, illustrated in the accompanying drawings and subsequently incorporate in the sub omed claims.

Fig. 3 is an elevation looking at right angles to Fig. 1;

Fig. 4 is'a diagrammatic view of the operating cams;

Fig. 5 is a similarview illustrating the movements of the thread carrying flier during one cycle in the winding operation.

Referring in detail to the drawings, 5 designates a suitable frame or bedplate having an upright= standard 6 on one of its ends in the upper end of which one end of a shaft 7 is journaled. Upon this shaft the spaced sprockets 8 are securely fixed, said sprockets being carried by a spacing collar 9 which is securely held upon the shaft 7 against lopgitudinal or rotary movement with respect thereto.

The sprockets 8 transmit movement to the vertically disposed endless link chains 10. Upon the corresponding alternate links of these chains the skein holders herein generally designated by the numeral 11 are securely fixed. These skein holders comprise no part of the present invention, as such holder forms the subject matter of my copending application for patent, Serial No. 346,837, filed December 23, 1919, to which reference may be had for a detail description thereof; For the purposes of the pres ent description it will suffice to state that this holder includes a body member 12 and a relatively movable member 13 which is pivoted upon the body member as at 14. The

ody member 12 is provided with bifur- 14 with an angularly disposed arm 17 with ing arm 21 having a'bearing sleeve 22 at its lower end in which the shaft 23 is journaled. Upon this shaft at each side of the bearing 22 a cam disk is securely fixed. These cam disks are designated 24 and 25 respectively. A cam rail 26, 27 is associated with each of these disks and conforms to the peripheral shap or contour thereof. The rails are disposed in spaced relation to the edges of the cam disks and are securely held in the plane of said disks by means of the'lugs or fingers 28 and 29 respectively which extend inwardly from the rails and are welded or otherwise securely fixed to the respective cam disks. Thus, there is provided between each rail and the edge of the cam disk a cam track 30 and 31 respectively.

Upon the depending part or bracket 32 of the frame or bedplate 5 a lever 33 is fulcrumed intermediate of its ends as at 34. The upper end of this lever which extends above the bedplate 5 is pivotally connected as at 35 between the ends of a sectional link 36. The other ends of the linked sections are formed with the mating halves of a I socket 37 to receive the spherical terminal or ball 38 on a rod 39 which is fixed in the end of the shaft 18 by means of the set screw 40. Thus, it will be evident that the shaft 18 may freely rotate with respect to the sectional linked connection between said shaft and the-lever 33. Upon the lower end of this lever 33 a roller 41 is-mounted and is positioned in the cam track 30'between the I periphery of the disk 24'and the rail 26.

To the lower end of the bracket 32 one end of a lever142 is pivotally connected as at 43. This lever is disposed horizontally and is provided intermediate of its ends with a roller 44 which is disposed in the other cam track 31 between the cam disk 25 and the rail 27. To the other end of the lever 42 the. lower end of a rod 45 is pivotally connected. A. collar 46 is clamped or otherwise.

securely fixed on the shaft 18 between the bearings 19 and the upper end. of the rod 45 is connected to this collar by means of the universal ball and socket connection 47.

In the operation of the apparatus as above described it will be understood that an intermittent movement is imparted to the sprocket chains 10 to successively dispose the skein loop.

holders carried by said chains at the upper sides of the sprockets and the cam mechanism for actuating the flier 20 is operated holders. This automatic control mechanism whereby the operation of the flier and of the carrier for the skein holders is properly timed or synchronized forms the subject matter of my copending application, Serial No. 346,836, filed December 3, 1919.

During on complete cycle of movements the winding mechanism winds upon the skein holder :1 skein comprising a main or primary loop and a plurality of intermediate or subsidiary loops. The main or primary loop is the loop which passes completely around the skein holder. The subsidiary or intermediate loops are those that are formed within the main or primary loop. The main or primary loop is first partially formed, the intermcdiate'or subsidiary loops are then wound, and the main or primary loop is then completed. The movements of the flier arm 20 in winding the thread upon the holder is clearly shown diagrammatieally inFig. 5. At the beginning of the winding operation the rollers 41 and 44 are disposed in their respective cam paths as shown in Fig. 4. In the initial movement of the flier arm 20 the thread is carried transversely of the skein holder between the bifurcated arms 14 to form one side of the main or primary This movement is effected through the medium of the lever 33 which is actuated by the cam 24. In this movement of the lever, the shaft 18 is shifted axially through the medium of the link 36. In the next operation, as shown in Fig. 5, the end of the flier carrying the thread is moved longitudinally of the skein holder to engage the thread in th bifurcated end of the holder arm 15 and thereby form a second side of the main or primary loop. As this arm is disposed intermediate of the plane of the arms 14', it is obvious that in order to secure a tightly wound skein, the flier arm must also be moved transversely of the skein holder during such longitudinal movement. This operation is effected by the simultaneous action of the cams 24 and 25 upon the rollers 41 and 44. The cam 25 together with its cam rail acting on the roller 44 actuates the lever 42 and through the medium of the rod -45, the shaft 18 is rocked or rotated in 'its bearings at the same time that it is being be readily separated relation from the spaced arms 14 of th holder to the extremity of the arm 15. Finally the thread is carried back to the starting point in the actuation of the cams so that the main or primary skein loop is closed and the cycle of winding operations completed. be very rapidly ,wound and by looping the yarn or thread as seen in Fig. 5, I produce a skein in the form of a plurality of multistrand superposed loops. These loops may when the yarn or thread is to be used without entanglement of the strands with each other. Thus it will be apparent that with the use of a skein holder of relatively short length, by means of the improved mechanism. the thread is wound in such manner as to provide a completed skein of maximum length. \Vhen on skein has thus been wound, the carrier chains 10 are automatically actuated to position the next skein holder at the upper sides of the sprockets 8. In this movement of the carrier. the thread is drawn through the eyes on the'flier arm 20 as the holder carrying the completed skein moves below the end of the flier arm. I also contemplate, in the completed machine, providing mechanism for cutting the strand of thread extending between the skein holders, but as this mechanism likewise forms no part of the present invention, it is not herein illustrated or described.

From the foregoing description considered in connection with the accompanying drawings, the construction,manner of operation and several advantages of my invention will be clearly and fully understood. I have found in practice that the winding mechanism may be operated at very high speed to accurately wind the skeins in the manner above explained. I have herein referred to the sprockets 8 and the chains 10 as constituting the means whereby the skein holdera are successivelypositioned to receive the skein windings. It is, however, to be understood that if. desired, other carrier means for the skein holders may be substituted in lieu of the chains and sprockets. Likewise, 'in sofar as the subject matter of the present application is concerned skein holders of other form and construction than that referred to.

may be employed. However, the holder which I have herein shown permits the skein to b rapidly removed by the use of a suitable trip to engage arm 17 of the movable holder member simultaneously with the release'of the latch 16. When this holder member 13 is swung or-moved to a position at right angles to the fixed member 12, the skein loops may be readily disengaged from the bifurcated arms of. the holder members.

The cam construction and arrangement together with the operating connections between these cams and the rotary and axially- In this manner the skein may for supporting the thread carrier,

an automatic movable shaft provides a very simple and compact arrangement of parts, which are positive and reliable in action and not likely to easily get out of order. It will also be appreciated that in view of the very simple form of the mechanism which I have devised, the invention may be produced at comparatively small manufacturing cost.

Vhile I have herein shown and described one practical embodiment of my invention which has given highly satisfactory results in actual use, it is nevertheless to be understood that the apparatus may also be ex emplified in numerous other alternative constructions. Accordingly, therefore, I reserve the privilege of resorting to all such legitimate changes in the form, construction and relative arrangement of the several parts as may b fairly embodied .within the spirit and scope of the invention as claimed.
